Yeah!!!
It works launching android studio emulator and then running project from b4a debug.
Nice thought!
But i'd have liked to work only with b4a
...., so then:
01. I created avd 28 api from b4a avd manager "6in_Phone_Platform_28_google_apis_playstore"
02. I copied from Nexus_5_API_28.avd to 6in_Phone_Platform_28_google_apis_playstore path every file, except ini file, overwriting everything
03. start 6in_Phone_Platform_28_google_apis_playstore b4a emulator and "wow! it works!!!" It shows just randomly errors from services but app run without problem. So now i can work only with b4a.
